Juro, I have not read Ed's book yet, but I plan to get both of his casting treatises soon.
I recently had the great fortune to spend three days with Ed & Lefty at Pintail Point in Maryland with about fifteen of the guys from TFO. One of the best weekends I have ever had, just messing about with fly rods for 72-hours. Ed understands the cast as well as any man I have ever met, and was able to give me two things that gave my casting more improvement than anything I have learned in years.
Ed is really keen to become a master of the two-handed rod as well. I am willing to bet that you two could work out an information exchange that would be beneficial to both parties.
Drop me an e-mail if you would like his contact info:
